I really dislike the tone of the explanation. I mean it's so negative about the features! Not that they are all useful, but isn't this a wiki and should be neutral? It takes also the fun out of it.

Travelling at above the simulated speed of light should give an imaginary time dilation, not a negative time dilation.&lt;br /&gt;
gamma = 1/sqrt{1-v^2/c^2}&lt;br /&gt;
Thus, after such travel, the value of the clock would be a complex number. [[Special:Contributions/108.162.219.35|108.162.219.35]] 15:42, 2 May 2014 (UTC)&lt;br /&gt;

'''Changed the speed of light to 2.99x10^8'''&lt;br /&gt;
:You guys should probably clarify that the relativisic affects actually depend on how long your trip is or how long you wait to sync your phone.  For relativity to be observable on a 12 hour trip, Minimum speed for a phone would have to be 300 m/s or 3000 m/s for the clock to measure even a microsecond/millisecond difference in time. This is well known thanks to the certain  [https://en.wikipedia.org/wiki/Time_dilation#Velocity_and_gravitational_time_dilation_combined-effect_tests time dilation experiments with planes]. Your GPS chip helps account for an error of [https://en.wikipedia.org/wiki/Error_analysis_for_the_Global_Positioning_System#Relativity 7 to 47 microseconds per day]. My point is in terms of time dilation, relativity mattering depends on how long a trip or waiting for synchronization is. By synching, I literally mean with the atomic time clock or with a GPS satellite. The synchronization of your phone with satellites is actually a couple of hundred microseconds, so normally even a light changing clock might not have as noticable changes as you might think.

; relativistic effect&lt;br /&gt;
Forgive me if I'm wrong, I'm not a physicist but the above explanation says that relativistic time dilation affects only occur at a significant fraction of the speed of light. It is my understanding that time dilation occurs at any speed, but is only perceptible/noticeable/measurable at very large fraction of the speed of light. Unless I'm mistaken the above it should reflect this. [[Special:Contributions/173.245.56.91|173.245.56.91]] 22:24, 2 May 2014 (UTC)&lt;br /&gt;

; putting &amp;quot;Relative&amp;quot; back into relativity&lt;br /&gt;
First time poster, please forgive my transgressions :)&lt;br /&gt;
My understanding regarding relativistic effects is that, for a given frame of reference (e.g. phone operator travelling at 0.9c) would be absolutely none. Relativistic effects (as I understand them) would only apply between two different frames of reference. The only effect I can see in this case is if you are moving towards, or away from the phone while operating, and red/blue shift of the radio frequencies. In general, wifi and bluetooth are used locally so wouldn't apply; only the phone network would be affected.&lt;br /&gt;
&lt;br /&gt;
Also, perhaps the adjustable speed of light is a reference to the the game &amp;quot;A slower speed of light&amp;quot; by MIT Game Lab http://gamelab.mit.edu/games/a-slower-speed-of-light/ (in which you walk around collecting objects; each object slows light down, and increases relativistic effects).&lt;br /&gt;

I am not a native speaker of English.

&amp;quot;Your mobile world just went digital&amp;quot; is an inversion of the marketing-speak that was common when what we'd now regard as smartphones first began to be adopted by the mainstream (iPhone/G1 era, since Symbians, Blackberries, and early WinMo tended to be business or enthusiast devices). People already ubiquitously e-mailed, browsed the Web, etc...what was presented as 'new' was that you could now do it from your phone.

I think the &amp;quot;Under certain circumstances, wireless transmitter may control God&amp;quot; statement might be a reference to how transmitting devices have to comply with FCC regulation and not interfere with aircraft or government communications.

'''Alternative meaning: The spirit of xkcd'''&lt;br /&gt;
&lt;br /&gt;
I think there's a secondary possible interpretation for this comic -- that the various features of the phone represent the overall &amp;quot;spirit&amp;quot; or &amp;quot;attitude&amp;quot; of xkcd, in a way reminiscent of an early strip -- http://xkcd.com/207/ -- about &amp;quot;what xkcd means.&amp;quot; More specifically, a common theme in xkcd is taking advanced concepts in science and technology, and applying them to whimsical, humorous, impractical, or outright impossible uses. Several of phone's features -- such as the simulated speed of light -- touch on the same theme. Wordplay, another common xkcd theme, is present as well; and the anthropomorphism of technology, along with making devices appear 'cute', is also present, and also is something that has come up in xkcd many times in the past.&lt;br /&gt;
&lt;br /&gt;
The comic is called &amp;quot;xkcd Phone&amp;quot;, after all -- I think simultaneously with being a parody of phone advertisements, the comic is also meant to show us what a phone that fits into the xkcd world would be like.

==Explanation==&lt;br /&gt;
{{incomplete|More detail; characters' motivation, etc.(?)}}&lt;br /&gt;
&lt;br /&gt;
The probe {{w|International Cometary Explorer|ISEE-3/ICE}} is a spacecraft launched on August 12, 1978. The original mission was to study the interaction between the Earth's magnetic field and the solar wind. It was later sent to visit Comet {{w|21P/Giacobini–Zinner|Giacobini-Zinner}} and became the first spacecraft to do so by flying through a comet's tail.&lt;br /&gt;
&lt;br /&gt;
Its trajectory will bring it close to Earth on August 2014. A status check of the spacecraft has revealed that many of its instruments are still working and that it contains plenty of fuel. But the hardware to communicate with ISEE-3/ICE has been decommissioned, and it will be expensive to reestablish the communication needed to use the spacecraft for another mission.&lt;br /&gt;
&lt;br /&gt;
The characters Crash and Burn (and the formers catchphrase, &amp;quot;Mess with the best, die like the rest&amp;quot;) are an allusion to the 1995 movie [[wikipedia:Hackers (film)|Hackers]]. Since the movie predates the shutdown-signal (1997), the characters should both possess the skills and 'outdated' equipment to understand and hack the signal to the probe.&lt;br /&gt;
&lt;br /&gt;
In the comic, Burn has hacked into the satellite and left the catchphrase to be shown to those who would log into the satellite regularly. She has also rerouted its path to enter the atmosphere at a certain time. She then uses this knowledge to tell Crash in advance at just the right time that a &amp;quot;falling star&amp;quot; will appear in the sky.&lt;br /&gt;
&lt;br /&gt;
The title text &amp;quot;Hack the stars&amp;quot; is also an allusion to the movie [[wikipedia:Hackers (film)|Hackers]] where the Phrase &amp;quot;Hack the Planet!&amp;quot; is used on multiple occasions.&lt;br /&gt;

:Burn: Make a wish.&lt;br /&gt;
:[Panel 16 shows the spacecraft streaking across the sky, indistinguishable from a meteoroid.]&lt;br /&gt;
&lt;br /&gt;
==Trivia==&lt;br /&gt;
*There are several pools in the movie as well. There is a subplot involving a mythical pool on the roof of the high school where several of the characters are students. Additonally, a scene in the movie [http://www.youtube.com/watch?v=dcHBsB0igrg Hackers Ending] shows Crash and Burn swimming in a rooftop pool, while several buildings light up with the words &amp;quot;CRASH AND BURN&amp;quot;, the result of their friends' latest hack. This scene is similar to the last four panels of the comic.&lt;br /&gt;
*The number of the comic is also significant, in that [[:Category:1337]] is a common numeric form of [[wikipedia:Leet|l33t]], again referring to hackers.&lt;br /&gt;

}}&lt;br /&gt;
&amp;lt;/div&amp;gt;&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
{{incomplete|Too many guesses, too many parentheses, maybe more. The time zones need an explanation.  The gif is way too fast, a minute would be better}}&lt;br /&gt;
The picture is divided in 24 segments representing the 24 hours of the day.  The break between segments is not visible at noon or midnight because of the words, but presumably exists.&lt;br /&gt;
&lt;br /&gt;
The picture rotates by 3.75 {{w|degree (angle)|degrees}} every 15 minutes, as does the Earth, so that it is constantly up to date in showing which regions are currently at which times of day. The picture change seems to happen half-way through a 15-minute time increment (that is, at 7½, 22½, 37½, and 52½ minutes after each hour), so that the picture is always correct for the nearest multiple of 15 minutes.&lt;br /&gt;
&lt;br /&gt;
The map projection of the earth in the middle of the picture shows an {{w|azimuthal equidistant projection}} with the {{w|South Pole}} in the center which is uncommon because most times this projection has the North Pole at its center. [[Randall]] was playing on projections before here: [[ 977: Map Projections ]].&lt;br /&gt;
&lt;br /&gt;
The list of cities and countries doesn't always match the map, because the list takes into account local variations in {{w|time zone}}s.  The map shows the current (February 2014) configuration of time zones with respect to {{w|daylight saving time}} (also known as summer time), which is  being observed at the time of the comic's initial release in parts of Australia, New Zealand, Brazil, and other countries not named in this comic. If the map is to stay accurate through the year, the location of place names will have to move over the next few months as parts of the southern hemisphere go off DST and parts of the northern hemisphere go onto it, but we don't yet know whether this will happen.&lt;br /&gt;
&lt;br /&gt;
In many countries, {{w|business hours}} are considered to be from 9&amp;amp;nbsp;am to 5&amp;amp;nbsp;pm. With some exceptions, including emergencies, it is generally considered rude to place a {{w|telephone}} call to someone's residence during the hours when most people are asleep (Randall portrays this time period as extending from 10&amp;amp;nbsp;pm to 8&amp;amp;nbsp;am).  This may be a reference to the 10&amp;amp;nbsp;pm &amp;quot;cutoff&amp;quot; time [http://www.youtube.com/watch?v=L0WeQJW-H3Y discussed] in an episode of &amp;quot;Curb Your Enthusiasm.&amp;quot; &lt;br /&gt;

==Technical notes==&lt;br /&gt;
When first posted, the picture was exactly 12 hours off. Somewhere around 5:10 UTC, this was fixed.  The original version also included a listing for Inland Brazil; this could have created a conflict with US East Coast when Daylight-Saving Time begins in the US, and it has been removed.&lt;br /&gt;
&lt;br /&gt;
The names used for the image files refer not to {{w|Universal Time|UTC (Universal Time)}} as one might expect but rather to the time exactly 12 hours off of that. The name of the image file linked from the page matched Universal Time during the first few hours, but the file-naming scheme did not change when the comic was corrected.&lt;br /&gt;
&lt;br /&gt;
==Transcript==&lt;br /&gt;
{{incomplete transcript|The table should be removed by a more simple way for showing the content here. And the table is incorrect.}}&lt;br /&gt;

&lt;div&gt;I really hate when articles on science get a POV tag.  Science isn't politics (hint: evolution and gravity aren't POV either).  Related to the comic, I just had a similar rant on Facebook in the last week or two where I linked to [http://www.skepticalscience.com/print.php?r=54 this article] when someone said it was too cold for Global Warming. [[Special:Contributions/108.162.237.64|108.162.237.64]] 12:24, 24 January 2014 (UTC)&lt;br /&gt;
&lt;br /&gt;
I really hate it when people think the global warming scam is science, when it really is nothing more than politics masquerading as science.  The IPCC has been proven to be a bunch of liars, and really there's nothing left but a bunch of whining left-wing lunatics who are desperately clinging to their hope of continuing to use this lie to raise energy prices/taxes. [[Special:Contributions/108.162.219.17|108.162.219.17]] 12:55, 24 January 2014 (UTC)&lt;br /&gt;
:Well you're wrong, and apparently delusionally paranoid about what the political left wants, but the bigger question is why is this in a wiki discussion page? [[Special:Contributions/108.162.249.117|108.162.249.117]] 13:21, 24 January 2014 (UTC)&lt;br /&gt;
::No, ''you'' are wrong, and still buying into the AGW myth that has been proven false (IPCC and others were basically caught lying).  Why is this in a wiki discussion page?  Well, apparently Randall has decided to use his webcomic as a vehicle to promote a left-wing agenda, so discussion of it here is totally legit. [[Special:Contributions/108.162.219.17|108.162.219.17]] 14:03, 26 January 2014 (UTC)&lt;br /&gt;
&lt;br /&gt;
Although it doesn't directly mention it, this is partly related to people's confusion over the difference between 'weather' and 'climate' - the former being what the conditions are at a given moment in time, and the latter referring to long-term trends.[[Special:Contributions/141.101.98.228|141.101.98.228]] 14:52, 24 January 2014 (UTC)&lt;br /&gt;

I think the one with whit wolly hat is whitehat [[User:Halfhat|Halfhat]] ([[User talk:Halfhat|talk]]) 16:10, 24 January 2014 (UTC)&lt;br /&gt;
&lt;br /&gt;
Randall has cherry picked data for his conclusion and the graph in the comic.  The full history is available from the NWS.  The one for my home town can be found here http://www.erh.noaa.gov/iln/climo/below0.php  The 1970's were unusually cold, which makes the present seem warmer by comparison. --[[Special:Contributions/108.162.210.254|108.162.210.254]] 16:33, 24 January 2014 (UTC)&lt;br /&gt;

Apparently Randall hasn’t seen this:&lt;br /&gt;
http://upload.wikimedia.org/wikipedia/commons/f/f5/All_palaeotemps.png&lt;br /&gt;
&lt;br /&gt;
To quote Michael Z. Williamson:&lt;br /&gt;
29 years in the last century is not an &amp;quot;average&amp;quot; of the last 300 million years.&lt;br /&gt;
&lt;br /&gt;
Any finding based on that &amp;quot;average&amp;quot; is complete bullshit. You may as well use 1300-1305 hours on Apr 23 as your &amp;quot;average.&amp;quot; You'll be about as accurate, and save time over actual data collection. {{unsigned ip|173.245.55.67}}&lt;br /&gt;
&lt;br /&gt;
The claim that 0 Fahrenheit / -17 Celsius is ''really fucking cold'' is supported by [[526: Converting to Metric]]. [[User:Fryhole|Fryhole]] ([[User talk:Fryhole|talk]]) 00:41, 25 January 2014 (UTC)&lt;br /&gt;
:We've been getting some ball-chilling winter with the cold fronts suddenly appearing in Florida, which is a drastic change from the sweaty weather just last week.
